DRYING-CYLINDER FOR TEXTILE MACHINERY.

SPECIFICATION formingpart of Letters Patent No. 755,354, dated March 22, 1904.

Application filed January 19, 1904. $erial No. 189,661. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. BUTTER- WORTH, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in Drying-Cylinders for Textile Machinery, of which the following is a specification.

My invention has reference to drying-cylinders for textile machinery; and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof. V

My invention has for its object the Withdrawal of the water of condensation from the drying-cylinder during its operation or when at rest, the operation taking place equally well under both conditions.

In carrying out my invention I provide the cylinder on the inside with a hollow dischargebearing arranged centrally in one of the cylinder heads and combine therewith a down wardly-hanging discharge-pipe, the upper end of which is loosely journaled upon the hollow discharge-bearing and the lower end opening into the cylinder close to the bottom thereof. The steam admitted to the cylinderat one end forces the water of condensation upward through the depending discharge-pipe and out through the hollow bearing.

My invention will be better understood by reference to the drawings, in which Figure 1 is an elevation of a drying-cylinder with a portion broken away and showing one form of my invention. Fig. 2 is a sectional elevation of the water-discharging devices,

taken on line 2 2 of Fig. 3. Fig. 3 is a crosssection of same on line?) 3 of Fig. 2; and Figs. 4 and 5 are views similar to Fig. 2, showing different modifications of my invention.

A is the drying-cylinder. B is one of its hollow journals fitted to the hollow pedestal G of ordinary form, and D is the other hollow journal fitted to the other hollow pedestal E of ordinary form.

The hollow journal D opens through the head of the cylinder bearing-stud F, which may be screwed or otherwise held in place. Loosely journaled upon this bearing-stud F is a-hollow head H, forming the annular chamber h, surrounding the stud and communicating with its interior by ports G. Screwed into this head 1 the bearing-stud F, but with insufiicient force to prevent the head and pipe remaining stationary when the cylinder is rotated. It will now be seen that the Water of condensation will be forced up the pipe K and through the bearing-stud F into the hollow bearing D whenever it accumulates sufficiently to submerge the lower end of the said pipe K.

In the construction shown in Fig. A the shoulder of the bearing-stud is placed upon its outer end, as at L, and the head H is held in place by screwing the stud F into the cylinder-head. This dispenses with the necessity of the washer I and nut J.

In Fig. 5 I have shown the general construction similar to Fig. 2; but the bearing-stud F is provided with a tapering bearing-surface, as at F. The hollow head H is likewise made tapering to fit this tapering bearing-surface F of the stud. The inner shoulder L does not come into play, because the tapering construction of the parts obviates the necessity therefor. V

While I prefer the construction herein set forth, I do not confine myself to the details thereof, as they may be modified in various ways without departing from the spirit of my invention.

Having now described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In a drying-cylinder for textile machinery, the combination of the cylinder having hollow bearings, a hollow bearing-stud provided with ports and having a shoulder at its outer end and also fastened into the hollow bearing at one end of the cylinder, and a discharge-pipe having a hollow head loosely journaled upon the hollow bearing-stud and held in position by the shoulder and its end extended close to the bottomof the cylinder.

2. In a dryingcylinder for textile machinery, the combination of the cylinder having hollow, bearings, a hollow v bearing-stud provided with ports and having a shoulder at its outer end and also fastened into the hollow bearing at one end of the cylinder, and a discharge device consisting of a hollow head having annular chamber in and loosely journaled upon the hollow bearing-stud and held in position by the shoulder and a pipe screwed into the head and having its end extended close to the bottom of the cylinder.

3. In a dryingcylinder for textile machinery, the combination of the cylinder, with an inwardly-projecting hollow stud centrally secured to one end of the cylinder for discharging the water of condensation and having a perforated cylindrical portion, a head loosely j'ournaled upon the stud and inclosing the perforations thereon while permitting free flow of Water through them, and a discharge-pipe secured to the hollow head and extending close to the bottom of the cylinder, the head and tube under the action of gravity retaining a substantially stationary position during the rotation of the cylinder and at all times being in condition to permit the discharge of the water of condensation.

In testimony of which inventionI hereunto set my hand.
